A four stage evolution of the White Channel gravel: Implications for stratigraphy and palaeoclimates [PDF]
Although the White Channel gravel (WCG) of the Klondike district, Yukon, contains gold placers which have been exploited for over a century, few sedimentological studies have been undertaken.

Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Impact of Mid‐Pliocene Boundary Conditions on the Atlantic Meridional Overturning Circulation (AMOC)
We use the coupled atmosphere‐ocean model MIROC4m to investigate the effect of mid‐Pliocene boundary conditions on the Atlantic Meridional Overturning Circulation (AMOC), studying the impact of increased CO2, reduced ice sheets and altered orography and ...

Pliocene and Pleistocene [PDF]
As you quote in NATURE of February 21, p. 278, from a note of mine printed in No. 6 of Natural History (American Museum of Natural History), will you allow me to state that the note quoted was not submitted to me in proof by the editor of Natural History. The part you quote embodies a serious misprint.

Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Pliocene Warmth and Patterns of Climate Change Inferred From Paleoclimate Data Assimilation
As the last time period when CO2 concentrations were near 400 ppm, the Pliocene Epoch (5.33–2.58 Ma) is a useful paleoclimate target for understanding future climate change. Existing estimates of global warming and climate sensitivity during the Pliocene

ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical
